Ok, first things first, we need to get you sleeping more hours than 5, about 8-10 since you seem to sleep long hours. The main concern is your not getting enough sleep to what your use't to, this is a health risk, your immune system will be weakened by the lack of sleep increasing the chance of catching something, it also will affect day to day stuff.
The way the body needs to be introduced into this is backwards, so you only go to sleep when your sleepy which is what you should be doing, but also set the alarm for 9. The reason for this is to get your body to make you go to sleep earlier not the other way round. So you go to sleep only when your tired say but get woken up at 9.
So your basically using all the fuel in your body and only restoring a bit of it, when that's all used up which is earlier than a full tank would be, you restore a little bit more until you reached a full tank.
A dream is a fantasy, if you achieve that fantasy it was never a dream to begin with.
